i 5 the county of Cuyahogaand State of Ohio,

have invented cert in new and useful lms provernents 1n Nozzles, ofwhich the following is a specification.

This invention is a nozzle for hose pipe or 10 street sprinklers, and isp: "'leularly adapted for use for's'treet lc ig or flushing, and has forits obj-1;. to provide a nozzle front which Will'fiow a wide sheetofwater at an angle suitable to spread'waterover a large '15 area, andin a single plane in such a manner as to be particularly useful forflushing large surfaces such as streets or the 11* i The invention isillustrated partying drawings, in which- Figure 1 is a side elevation.of the nozzle.

of'Fig. 1. the direction of the arrow (1, Fig. 1. Fig. a is an edge Viewlooking in the direction. of the Fig. 5 is a perspective. Fig. 6 is arear end view.

I Referring specifically to the drawin s, t3 indicates a Water supplypipe leading rroin the Water tank or reservoir.

projects from a shoulder 10 at the rear of the nozzle. nozzle are curvedoutwardly, or concave on the inside, and in connection with the endwells 7 form an enlar ed hollow or chamber 16 therein. The walls 9 areflared or spread laterally and curved toward each other to form alongnarrow mouth or slot between the lips 14.

the other, and the line of the lips M is at an angle to theperpendicular from said axis, so that the lateral extension of thedischarge slot is greater on one sideof the axis than on the other sothat the Water spread on one side more than on the other, as will heclearly apparent from F 1. Also, one of the side walls 9 is curved to agreater extent than the other so that they discharge slot is offset,
